IMPROVEMENT IN PRESERVE-CANS.

Specification forming part of Letters Patent No. 36,264, dated August19, 1862.

T0 aZZ whom it may concern:

Be it known that I, HENRY S. FIsHER, .of Newburg, in the county ofCumberland and State of Pennsylvania, have invented a new and ImprovedPreserve- Can; and I do hereby declare that the following is a full andexact description thereof, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, like lettersindicating the same or analogous parts, and in which drawings.

Figure l is a sectional view of my improvement; Fig. 2, a plan view ofthe same; Fig. 3, a plan view of the top of a preserve-can with a capthereon made according to my'present improvement; and Fig. 4, a sectionof the plan view shown in Fig. 3. Fig. 5 shows an approved form ofconstructing the body of a preserve-can, and an approved mode of apply--ing a tubular screw-cap thereto shown in perspective in Fig. 6. Figs. 7,8, and 9 are also views showing preserve-cans and approved modes ofsecuring the caps to the top of the same, Figs. 5, 7, 8, and 9 all beingviews of preserve-cans with modes of fastening on the sealing-cap,adapted for use in case transpon tation for long distances is necessary.l

I would state that the devices shown in Figs. 5, 6, 7, S, and 9,although of an excellent character and which may furnish hereafter thesubject-matter of separate and distinct applications for patents, do notin this my present application form the subject-matter for a patent.

The subj cot-matter of this patent is particularly shown and designatedin Figs. 1 and 2 of the drawings; and it consists of a circularformedcan, a, having at its top an orifice, b, of circular form for ingress toand egress from the body of the can. The edge of this orifice b isturned up, as at 0, above the surrounding main portion (2 of the top ofthe can, in order that a fillet, g, of paper saturated with beeswax orother proper material which is hard and non-adhesive when cold but whichwill become adhesive under a gentle heat, may be applied on top of theelevated edge 0, as shown, and be pressed around the side of saidelevation, as at f, and also on top of the can at portions marked d. Thefillet marked 9 is shown in proper position in Fig. l, with the canscaled up, and is immediately held in place by a peculiar-formedcan-cap, H. This cap is formed by simply cutting out a disk of propersize from a sheet of tin, and then with a proper tool a bulge or oval orspherical projection, z, is formed in its center, as indicated in Figs.1, 3, and 4, leaving the surrounding portions of the cap flat, as at a?in said figures. This oval projection, as will be seen in Fig. 1, is atits base just of a proper diameter to fit over the projecting edge 0.,and when placed in position, as shown in Fig. 1, presses down the fillet9 upon the top of 0 as well'as causing the fillet to hug the outer sideof c,

and also to be snugly pressed upon the portions (1 of the top of thecan. The oval projection of cap H just named also serves as an elevatedpoint over which to spring a bar, 76, one end of which is inserted in aloop, Z, and the opposite end sprung down beneath ahook, m, as shown inFigs. 1 and 2.- By thus constructing the cap H, the necessity for theinsertion of wedges between the cross-bar and the can-cap, as heretoforedone, and the trouble arising from the loss of the wedges, is obviated.Beside this difficulty, the shrinking of wooden wedges ordinarily used,and a consequent leakage of air into the can from such cause, is alsoavoided by such mode of constructing the can-cap, to say nothing of itssimplicity and cheapness.

Having reference to Figs. 1 and 2, we will suppose the can-cap to beremoved, and that the body of the can has just been filled withpreserves in the usual heated state. Theoperator then lays the fillet 9over the orifice b, the heat of the body of the can causing the adhesivequality of the fillet to become developed. The can-cap H is then placedupon the fillet, as represented in Figs. 1 and 2, and the rod isinserted in the loop Z and sprung down beneath the hook m, its centralportion resting upon the bulge i, as shown. This operation causes thebase of the bulge z to llllpinge upon the fillet, causing the latter tohug the sides and top of the elevated portion 0 and be drawn taut overthe mouth or orifice b of the can, as well as, causing the fillet to befirmly pressed upon the main top portion, (i.

In this manner it will be seen that the fillet g is caused to have anairtight-joint contact with the main top of the can at three points,allof which are in different planes, and by means of which the canbecomes effectually sealed.

I would here state that the fillet 9 may be made of paper saturated withbeeswax, as

before stated; or the adhesive material may be made of a compound ofcoal-oil and resin. Having thus described my said invention,

' what I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. The cancap H, constructed with the plane portion cl and bulge portion2', in connection with a can-top having a central orifice through it,all substantially in the'manner and for the purpose specified.

2. The combination of the cap H, constructed as described, pan-top, andclamp 70, substantially in the manner and for the purpose described.

3. The cap H, in combination with the orifice-elevation a and fillet g,in the manner and for the purpose substantially as described.
